Story
Haiba Sumio is a student at a Tokyo High School with an interesting ability... He occasionally falls asleep and wakes up with premonitions of the future written out on his "Dream Diary".

Characters
A first-year student, class A, and the main male protagonist. His ability is the Dream Diary. He refers to the Dream Diary as a way to help change the current fate and when people are in trouble he refers to it as a MAYDAY. After being taken into the E-Test, Sumio becomes the de facto leader of the group, as he appears to have the most training with his ability and possesses a willingness to help others in danger. It has been since revealed that his actual ability is telepathy, and that combined with Shigeru's precognition allows him to record the future.
A first-year student, class A, and the main female protagonist. Her ability is precognition, which when combined with Sumio's telepathy allows the Dream Diary to work. Shigeru is Sumio's childhood friend. Despite this, Sumio, or herself, never knew she had an ability and openly wonders why Shigeru is taking the E-Test.
A second-year student, class H. When he was captured he was in a costume he was wearing for a part-time job as a police mascot. It's later revealed that his ability allows him to transform in his costume, called Pit-Kun. With his ability, he can also change his size, growing to huge proportions and even fly. He discovered his ability after he was in a tragic accident, leaving his body practically immobile. But after being inspired by the heroics of Pit-Kun, he transformed into the character and dedicates his life to save people.
A first-year student, class E. A member of the baseball team, his ability is to make things turn invisible/disappear when frightened, introduced in chapter 2. This doesn't extend to just physical objects, as he can also make people in photographs disappear to see what is behind them. He refers to his power as a curse and has a strong desire to get rid of it, however after seeing his ability being useful to the group, his opinions change. His motto is that he always takes the safest path in life.
A third-year student, class B. His ability is Cubic Subtraction, introduced at the end of chapter 8 and explained in chapter 9. With this ability he can reduce the measurements of objects at his will. The only conditions of this ability are that he cannot add to the object and it does not affect humans. He is the first in this E-Test to be captured by a Shadow. Once he was saved, he had the choice to swallow a pill to stop the Shadow transformation. Instead of swallowing the pill, he saves it to force Kurisu Ryo to take it and save him. It is explained that he has already taken place in a past E-Test as the sole survivor and wanted to take place in another to save Kurisu, who was trapped.
A second-year student, class C. Her ability is an invisible third hand introduced in chapter 4. With the third hand, she can move small objects and often uses the ability to check each room for safety reasons. Despite being invisible, the hand always leaves small hand prints among the surface of what it touches. Her family is apparently a zaibatsu that had ties to the Queen Airlines plane crash, so she was originally a loner and preferred to keep to herself while using her ability to prevent the other students from playing cruel pranks on her. She seems to be developing feelings for Sumio.
A third-year student, class G. His ability allows him to "rewind" things making them return to the past. It is introduced and explained in chapter 26. He is very strong but stubborn. Due to his stepfather's abusiveness (an episode of which caused the large scar on his back that is the root of his powers) and being forced to apologize for no reason, he has an intense disdain for anything irrational.
